[GIT PULL] parisc architecture fixes and updates for v7.1-rc1

Hi Linus,

please pull fixes and updates for parisc for kernel 7.1-rc1.

One important fix to unbreak modules on 32-bit parisc, which were broken
since kernel v6.19. The other changes are just smaller maintenance cleanups.

Thanks!
Helge
